Estados limite de servicio en relacion con la via en puentes de ferrocarril

Serviceability limit states in track on railway bridges

Un puente de ferrocarril debe soportar, sin peligro de hundimiento, las diversas cargas que pueden actuar sobre el a lo largo de su vida. Pero no es suficiente constatar esa cualidad resistente, ya que su respuesta frente a esas cargas es una accion para la via y para los vehiculos que circulan por el puente. Es preciso controlar que la accion del puente sobre la via no sea una causa que produzca su desconsolidacion y que su accion sobre los vehiculos no implique niveles inaceptables de seguridad y calidad de marcha de las circulaciones. Por ello es preciso evaluar el comportamiento de los puentes ferroviarios en determinados aspectos geometricos y dinamicos, lo que exige diversas comprobaciones que deben realizarse desde su concepcion y que se indican en este articulo. (A). English abstract: A railway bridge must be capable of withstanding the whole range of loads which may act on the same throughout its working life without any risk of collapse. However, the control of this strength characteristic is not, in itself, enough as the response to these loads leads to action on the track and the vehicles travelling over the bridge. As such, it is necessary to ensure that the bridge action on the track does undermine the same and that the actions on vehicles do not lead to unacceptable safety levels or affect user comfort. It is, therefore, necessary to evaluate the behaviour of railway bridges in accordance with certain geometric and dynamic aspects and this article considers the diverse controls which have to be carried out from the time of original design.
